Is your daily life safe from chemicals?
Chemistry: An Excuse for That Fear

Not long after the humidifier disinfectant incident left us shocked and horrified with its numerous deaths and casualties, the pesticide-laced egg scandal and the detection of carcinogens and radon in sanitary pads and mattresses have also emerged.
In South Korea, accidents caused by chemical substances continue to occur every day.
With the controversy over harmful ingredients and the word "detection" continuously appearing on portals and newspapers, parents raising young children are experiencing days of anxiety about what to choose as a safe option.


So, are chemicals created by chemistry dangerous? The answer is, "In the right amount, in the right place, and used appropriately, they are safe."
Chemical substances that cannot be left out of our lives for even a single second, from the moment we wake up in the morning, when we wash our faces and brush our teeth, until we go to bed at night.
How should we deal with these substances, which are absolutely necessary but of questionable safety?


If you know chemistry (theory), you can see the dangers of chemistry!
Chemistry Stories from Professor Kim Min-kyung, a "Chemist"

"There's never been a chemistry book like this! Is this a science book or an essay?" This book, which explains chemistry in a comfortable and accessible way like an essay, brought to mind a famous line from a movie. It began as a course for humanities students at Hanyang University called "Chemistry in Everyday Life."
Professor Kim Min-kyung, who is also the subject of the chemistry expert meme that has been making a stir on social media for a while, is famous for her excellent speaking skills and talent, to the point that she has been selected as the Best Teacher by students every year since she started teaching.
Based on these experiences, “There’s a Chemist in My House” was published to the general public who were unable to attend lectures.


How can we approach chemistry so that even those who dislike or lack a strong understanding of it can understand it? This question can be easily solved by explaining the principles of chemistry through everyday chemical substances found in the space of "home."


Neutralization reactions, entropy, osmosis, the octet rule…
You, too, can become the 'chemist of our home' by reading this book!

The girl who wondered if the glacier Dooly rode on would taste salty while watching the cartoon [Dooly the Little Dinosaur] has now become a full-fledged chemist.
I still sometimes cringe at the fishy smell when grilling fish, or worry about which play mat to choose, or whether I should boil my laundry, but soon, using the knowledge I've accumulated as a chemist, I use vinegar to remove the fishy smell (neutralization reaction), go through a pretreatment process to remove any chemicals that may be left on the mat (chemical removal through ultraviolet rays), and try not to boil my laundry or boil it without detergent (diffusion of gases and changes in chemical state at high temperatures).
After reading this book, you too will become a 'chemist in your home' and live a safer life.
In addition, you will be able to demonstrate the chemical skills you have acquired in everyday life, such as neutralization reactions, osmosis, entropy, and global warming (climate change).
